Terms are the numbers and variables that are usually separated by an addition sign or a subtraction sign. In the expression 2x, 3y, 5z, and 4 are all terms.
Variables are the letters that come after a number. They represent the unknown number in the equation. The x, y, and z in the expression are the variables.
Coefficients are the numbers in front of the variables. For example, 2, 3, 5, and 4 are the coefficients.
The constants are the "signs" in between the terms. These include the addition sign and the subtraction sign.
This is proportion so we have to set it up as _/_=_/_
So we would set this up as 18/2=x/10
We multiply 5 on both side.
2x5= 10
18x5= 90
So answer is 90 donuts in 10 boxes.

Answer: $3.87
Step-by-step explanation:
3.10 increase 24.8% =
3.10 × (1 + 24.8%) = 3.10 × (1 + 0.248) = 3.8688
Answer:
51 meters
Step-by-step explanation:
Steve is turning half his backyard into a chicken fan. His backyard is a 24 m x 45 m rectangle. He wants to put a chicken wire fence that stretches diagonally from one corner to the opposite corner. How many meters of fencing will Steve need?
We are to find the meters of fencing for the diagonal.
We solve the question using Pythagoras Theorem
= c² = a² + b²
Where
c = Diagonal
a = Width
b =Length
Diagonal² = Width² + Length ²
Hence:
Diagonal ² = 45² + 24²
Diagonal = √45² + 24²
Diagonal = √(2601)
Diagonal = 51 m
Therefore, the meters of fencing for the diagonal that Steve would be needing = 51 meters
